A real shell on the chat's own connection, opened and closed like the
inspector and never beside it. The modes govern the model; what a person
types is theirs, since they hold the credential and could open the same
shell with an ssh client. The model cannot see the panel -- a button
copies the output you choose into the composer.
The session outlives the socket: closing the panel leaves a build
running, and coming back reattaches with the scrollback. Two tabs share
one shell and the smaller window decides the size. It ends on an idle
timeout, on deleting the chat, on disabling, moving or deleting the
connection, and on a restart -- which says why rather than quietly
opening a fresh shell that has lost the working directory.
The nginx template's `Connection ""` is right for SSE and fails every
WebSocket handshake, so `location /` now uses a `map $http_upgrade`;
update.sh grows a drift check for it, because the only symptom on a
stale vhost is a panel that cannot connect.

A third child of .shell, opening and closing like the sidebar opposite it,
showing the system message that would go out, the tools offered, what the
last reply cost, and the whole request body as JSON.
Rebuilt, not recorded. Recording every request would store a copy of the
growing conversation against every message -- quadratic in chat length -- and
the thing an administrator debugging a bad answer actually wants is what the
current configuration produces. The panel says exactly that at the top, so
nobody mistakes it for forensics.
Owner-checked and admin-checked, not admin alone. permissions.resolve giving
an admin everything is about configuration, which they can grant themselves
anyway; reading someone's conversation is a different act, and it is why
sharing.visible_to has no admin branch. An inspector that could dump any
user's transcript would be that branch under another name.
No new JavaScript. app.js already delegates [data-toggle], and
hx-trigger="intersect once" makes the load lazy for free: a hidden element
never intersects, so the request fires the first time it is opened and never
on a page load nobody looked at.
Image data URIs are replaced before dumping -- fidelity is the point, but not
several megabytes of base64 in the DOM. Everything renders through normal
escaping and never |safe: this JSON is full of model output, search results
and uploaded documents.

The brand accent was rune gold. It is now mallorn green: --gold becomes
--leaf in tokens.css and everywhere it resolved, and the mark's wafer is
the green of the leaves lembas travels wrapped in rather than the biscuit
inside. Yellow is left to mean exactly one thing in the interface -- a
warning -- instead of two.
Two knock-on choices the rename forced:
- Code keywords move from the brand accent to --warning. Strings are
--success, which is green; keywords in leaf green beside them is not
a colour scheme.
- --success itself leans teal now. Two greens a hue apart read as one
colour rendered badly, and an unread dot has to be tellable from a
brand badge at a glance.
The mark is redrawn, not just recoloured. The blade is ovate -- widest a
third up from the base, rounded where the stem meets it, drawn out only
at the tip -- because the old one was pointed at both ends and read as an
eye. It is also much larger relative to the tile: at 16px the silhouette
is all that survives, and a small leaf on a large tile is a green square
with a smudge on it. Veins sweep towards the tip and shorten as the blade
narrows. The score cross is thinner and fainter so it stays texture.
A single diagonal score was tried first and rejected: behind a diagonal
leaf it does not read as scoring, it reads as a line struck through the
mark.

Seven reported problems.
**Bulk model actions 404'd.** /admin/models/{model_id} was registered
before /admin/models/bulk, and FastAPI matches in registration order, so
"bulk" was parsed as a model id. Moved above the parameterised route,
with a comment saying why, and a regression test.
**Empty chats piled up.** There is now no endpoint that creates one.
"New chat" is a link to /chat, which renders a composer with no row
behind it, and POST /api/chats/start writes the chat together with its
first message. Opening one and walking away leaves nothing.
**Pinning meant two different things.** The picker is now always in the
administrator's position order; pinned models get shortcuts in the chat
sidebar and nothing else. A picker whose order silently differs from the
admin screen is just confusing.
**Model images were missing in chat.** Assistant bubbles now show the
avatar of the model that actually wrote the turn -- which is not always
the model the chat is set to now -- falling back to the LLeMbas mark.
The picker shows it too.
**No global or per-model system prompt.** Three layers now: instance
(Admin -> General), model (Admin -> Models), chat. Precedence, not
concatenation: most specific wins outright. Stacking them reads well in
a settings screen and badly in practice, because two layers that
disagree give the model contradictory instructions and nobody can tell
which is losing. The chat panel shows the inherited prompt as
placeholder text so "leave empty to inherit" is not a guess.
**Alignment and button sizing.** Added --control-h and friends to
tokens.css; every button, input and select takes its height from them,
so a mixed row is flush by construction rather than by per-instance
nudging. Icon buttons are square at that height. Added .btn-row,
.card__header/.card__footer and .grid so pages stop carrying inline
styles, and moved every admin page onto them.
**Settings needed structure.** The user settings page is now tabbed
(Account / Models / Appearance / Security) using radio inputs and
sibling selectors -- no JavaScript, and the browser keeps the chosen tab
across a re-render.
Caught while checking: the chat.css surgery had deleted the attachment,
chip and dropzone rules. Restored, and there is now a check that every
literal class used in a template has a CSS rule.
197 tests, ruff clean.

LLeMbas now runs end to end. Register, add an OpenAI-compatible
connection, and hold a real streaming conversation organised into
folders. Verified against the local llama-swap instance.
Streaming is the one genuinely tricky part. Sending a message returns
two HTML fragments -- the user bubble and an empty assistant bubble
carrying an sse-connect -- and that attribute is the ONLY thing that
starts a generation. Rendering an incomplete assistant message as a
streaming shell falls out of the same template, which means loading a
page whose last reply never finished simply picks it up again.
Details worth knowing about, each commented where it matters:
- SSE payloads are split across several data: lines. A raw newline in
one data: line truncates the event, which shows up the first time a
model emits a code block.
- Markdown is rendered server-side by the same helper for both the page
and the final streamed frame, so the two cannot disagree. The fence
renderer is replaced outright rather than using markdown-it's
highlight option, which re-wraps output in a second <pre>.
- escape_text is html.escape, not nh3.clean_text: it escapes character
by character, so escaping stream chunks separately equals escaping
the whole string.
- The stream opens its own session via session_scope(); it outlives the
request handler and the dependency-scoped session may be closed.
- Deleting a folder keeps the chats inside it (FK is SET NULL). Losing
a conversation to a mis-clicked folder delete is unforgivable.
- Login failures use one message for "no such account" and "wrong
password" so the form cannot enumerate registered addresses.
Also adds deploy/ for the gamebox install at https://chat.lan: system
unit, nginx vhost with buffering off (buffering on turns streaming into
one lump at the end), and install/update scripts following the same
service-user and /srv bind-mount conventions as llama-swap and comfyui.
70 tests, ruff clean.
